Ruby on rails 无法在Rails 4中使用bundle install命令安装capybara webkit

在Rails 4应用程序中执行命令

bundle install

时，我遇到以下错误

> ruby -v

> rails --version
Could not find gem 'capybara-webkit x86-mingw32' in any of the gem sources listed in your Gemfile or available on this machine.

Make sure that `gem install capybara-webkit -v '1.10.1'` succeeds before
bundling.

注意：我已经尝试查看一篇有类似问题的文章，并尝试通过执行以下命令来遵循解决方案。但出现了以下错误

> qmake -v
'qmake' is not recognized as an internal or external command,
operable program or batch file.

安装说明位于capybara webkit wiki-。您需要安装Qt 5.5.1（只有单独构建QtWebKit模块时才支持5.6）

我有OS X El Capitan系统。 我跟踪了这个链接：

然后

这个问题已经解决。

Ubuntu

sudo apt-get update
sudo apt-get install qt5-default libqt5webkit5-dev gstreamer1.0-plugins-base gstreamer1.0-tools gstreamer1.0-x

无法识别“qmake”

可能表示未安装Qt

brew update
cd $( brew --prefix )/Homebrew/Library/Taps/homebrew/homebrew-core
git checkout 9ba3d6ef8891e5c15dbdc9333f857b13711d4e97 Formula/qt@5.5.rb
brew install qt@5.5
echo 'export PATH="$(brew --prefix qt@5.5)/bin:$PATH"' >> ~/.bashrc

完整的安装过程是

我必须运行：

QMAKE="$(brew --prefix qt@5.5)/bin/qmake" gem install capybara-webkit

为了在我出错后安装gem：

qt@5.5：未知版本：mountain_lion

，并按照以下步骤进行评论：

注意：如果出现错误：qt@5.5：未知版本：mountain_lion，公式中的注释行#25/qt@5.5.rb

因为它应该执行以下操作：

从root开始安装gem-capybara-webkit-devel包：

导出编译所需的路径附加项：

$ export PATH=/usr/share/qt5/bin:$PATH

使用bundler安装gem

$ bundle

---

我已经这样做了（OSX High Sierra），但gem安装仍然不起作用：“哪个qmake”=>“/usr/local/opt？”/qt@5.5/bin/qmake“但是安装Gem给了我“Command'qmake'failed”@sixty4bit这不是这个问题所处理的错误，

Command'qmake'不可用

-所以这里真的不是问这个问题的地方。用比此处提供的更多的详细信息打开您自己的问题。如果出现错误：

error:qt@5.5：未知版本：mountain_lion

确保遵循文档中的注释：注意：如果出现错误：qt@5.5：未知版本：mountain_lion，公式中的注释行#25/qt@5.5.rb

$ export PATH=/usr/share/qt5/bin:$PATH

$ bundle
